DLL Path

[krtxmrtz]

I'd like to write:

Private Declare Sub MySub Lib App.Path & "\Mydll.dll" (MyParam As ...)

rather than

Private Declare Sub MySub Lib "C:\VB\Projects\MyProj\Mydll.dll" (MyParam As ...)

but unfortunately this is not allowed.

Is there any way round or some trick to make the declaration path a relative one? I like to keep the dll in the app (and not in the Windows) directory because I'm often making changes and updates to it.

If your dll is registered then it should not be necessary to declare the path as the default initial location windows looks for files is the applications path. Then in Windows. Then in System32. Basically a shortened enumeration of the locations windows looks.

I tried to register it but I got this message:

"...Mydll.dll was loaded but the DllRegisterServer entry point was not found"

Thats a different error then path not found. Did you use VB 6 to write the dll or is it a third party dll? Did you try it with the hard coded path and did it work?

Try using Depends.exe to determine any dependancies that may not exist or ??? if its a third party dll.

When you try it with the DLL in the application folder, do you recieve any error.

Private Declare Sub MySub Lib "C:\VB\Projects\MyProj\Mydll.dll" (MyParam As ...)

If it is a Win32 Standard DLL then it does not need any registration.

It should work even if the DLL is present in the same folder as your EXE.

Yes, thats what I thought that it did look in the application path folder first but it sounds like the error mesage is dll dependant and not a Declare type issue.

I wrote it in c++

It did, yes.

I believe it is possible to declare it like:

Private Declare Sub MySub Lib "Mydll.dll" (MyParam As ...)

VB should look in the application path as well.

VB should look in the application path as well.

It doesn't work either. Btw I've tried in VB6 under Win98.

Did you try this in the IDE or with an exe?
If you run the application from the IDE, windows regards the directory where VB6.exe is located as the application directory, and not the directory where your project is located.

You're right, it works after I've compiled it. But it's a nuisance having to cope with this from the IDE, as I'm still developing the project (and will be for quite long, probably) and I work on it from various computers having different pathes.
